Abstract

The utility model discloses a large-tonnage load box capable of remotely applying pressure and detecting displacement. A bottom plate (1), a top plate (2) and a waterproof sealing enclosing plate are enclosed to be a sealed space; a pressure exerting device (4) and a displacement meter bracket (4) are arranged in the sealed space, wherein a displacement meter (6) is arranged on the displacement meter bracket (5); a displacement signal output pipeline (10) which is connected on the displacement meter (6) is guided out through a top plate hole (3), a connecting pipe (7) and a pipeline guide-out pipe (8), so that the synchronous process for the pressure exertion and the displacement detection is achieved and a remote control is achieved, and the device is embedded in a sealed manner; the pressure and the displacement are loaded and measured in a multi-group manner, thus the device provided by the utility model can achieve loading the large-tonnage pressure and integrally measuring the displacement.

Description

The load box of displacement can exerted pressure and detect to a kind of large-tonnage at a distance
Technical field
The utility model relates to pressure and applies and the displacement detector technical field, particularly relates to the load box that displacement could exerted pressure and detect to a kind of large-tonnage at a distance.
Background technology
A lot of site inspection tests of geotechnical engineering industry and civil construction industry all can relate to pressure and apply problem; The formula of burying underground the pressure apparatus that particularly large-scale test in situ usually need provide far distance controlled to exert pressure, especially more outstanding in the pile foundation load test of the ragstone of karst landform.Whole world karst landform type distribution accounts for 12% of land surface, and the resident population has 1,000,000,000 approximately.China's karst landform type accounts for 10% of area, and distribution area is more than 90 * 104 square kilometres.Karst landform distributed area, China south is the maximum zone of distribution area in flakes, the whole world, and the most concentrated with Guizhou, Yunnan and Guangxi, and karst place, Guizhou Province accounts for 61.92% of the whole province's area.Karst landform distributed area ragstone foundation strength is high, and the pressure that foundation loading test need provide is big, and the pile foundation load test needs far distance controlled to exert pressure, and measures pile foundation displacement simultaneously and changes.Single jack is exerted pressure and is measured displacement with single displacement meter and not too be fit to large-tonnage pressure and apply and whole displacement detecting in the prior art.
Summary of the invention
The utility model technical problem to be solved is to overcome existing load box to be not suitable for large-tonnage pressure and to apply the defective with whole displacement detecting, provides a kind of large-tonnage can exert pressure and detect the load box of displacement at a distance.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The load box of displacement can exerted pressure and detect to large-tonnage at a distance; Surround a sealed space by base plate, top board and waterproof sealing coaming plate; In the sealing space; Be provided with pressure applicator and displacement meter support, on the displacement meter support, be provided with displacement meter, the displacement signal export pipeline that is connected on the displacement meter is drawn through roof hole, tube connector and pipeline fairlead.
Tube connector is a steel pipe and the pipeline fairlead is a flexible pipe, adopts the binding mode to connect between them.
Preferably, the pressure applicator in the aforementioned load box is the hydraulic amplifier device.
Preferably, pressure applicator is provided with more than one, thereby realization pressure is organized the function of loading more; The displacement meter support is provided with more than one, and a displacement meter support is provided with a displacement meter, organizes the function of mensuration to realize displacement more.
Compared with prior art; The utility model is enclosed in pressure applicator and displacement meter in the seal cavity through top board, base plate and waterproof sealing coaming plate; Realized exerting pressure and the carrying out synchronously and far distance controlled of displacement detecting; And this device can seal and bury underground, because pressure and displacement can adopt many groups to load the mode of measuring with many groups respectively, measures so the device of the utility model can be realized the integral body of large-tonnage pressure-loaded and displacement.
